Ah hell, I don't wanna do Physics so I'll explain both:

50mm f/1.8 vs 50mm f/1.4:
The IQ is the same between the two. The 50mm f/1.4 has more aperture blades so the bokeh is smoother, but if you're using it for product shots in a lightbox this is of little use to you. The 50mm f/1.4 also autofocuses faster (but not as fast as other USM lenses, since it uses micromotor USM whereas other lenses have ring-type USM) and has better build quality, both for the body and the metal lens mount (f/1.8 II uses a plastic mount). The 50mm f/1.4 also has a better manual focus ring whereas the f/1.8 has the manual focus ring at the end of the barrel. Finally, the 50mm f/1.4 has full time manual, meaning you can manually focus/adjust even with the gears set to AF.

In short: Similar image quality, better build quality and AF on the 50mm f/1.4


50mm f/1.8 vs 28mm f/1.8
The 50mm performs better wide open, in my opinion. The 28mm (or at least my copy) is soft wide open and has CA. This does affect IQ with a lightbox, and is why most of my product shots are stopped down to f/2.5-f/2.8. However, the 28mm has a wider focal length, so it can be used closer to the shots. With the 50mm, I often had to be ~4-5ft away from my subjects, whereas with the 28mm I can be 2 ft away (usually less than two feet). The 28mm also has ring-type USM so it autofocuses much faster and has full time manual, and the focusing ring feels much better in my opinion. The 28mm also has better build quality and better lens mount.

In short: 50mm has better IQ wide open, 28mm has a more useful focal length on crop, better build quality, and AF faster.



Oh, you
Thanks for that +rep to all

I think I'll get the 50mm F1.8 Mark II lens.

Also is the kit 55-220mm Lens ok for long range sport shots (25-50m) ETC?

And what do i need to make light sources look like stars? is it a polarizer?

Cheers - Jason.

The 55-250mm is great value and will give you good telephoto performance. It's hard to beat it for the price.

As for starburst effect, you'll need to stop down your lenses + long exposure.

The starburst effect here in my photo was done with f/10 and 30" exposure:


EDIT: Out of curiosity, how are you making your lightbox? What's the setup going to be for it?

Thanks for the help mate,.

For the LightboxMade it out of scrap wood around 60 x 60 x 60 . Used Plywood for edgings and applied White Cardboard all round the inside. Got two 50 x 50cm holes on the side and top covered with white silk cloth. So three 6000K Lights in total. Also got lots of acrylic base and backdrops, carbon fibre and brushed grey and silver aluminium for bases as well.

Cheers - Jason.

Where did you buy the bases? I may be interested in buying some.

Got all the Acrylic from "PLASTIX" they cut to size and charge reasonable prices , However you just need to find a local acrylic supplier. Google is your friend.
As for the Aluminium I used this guide for the silver and grey : http://forums.bit-tech.net/showthread.php?t=114028 . I then clear coated one of them and had the other one powdercoated grey-satin.
Carbon Fibre is 3M applied onto a wooden board.

I've been thinking of getting some reflective material for the base of my lightbox. How strong is acrylic? How much can I put on that before it cracks/break?

I got the 5mm Acrylic, It'll hold just about anything as long as you don't force it on (Literally dumping an object on it)

Besides using longer exposures, star filters work well too, especially under lighter conditions when you can't necessarily use long exposures.
